Exchange filtered email forwarding to External Contact

I have been wrecking my brain on this problem&.

Issue: Problem with getting an email from an external address A@hotmail.com emailed to a mailbox B@mydomain.com (Exchange 2003) and the message from this recipient forwarded to an external AD contact C@external.com.

I do not want to set Global Rules to allow automatic forwarding because I see this as a security risk because all users will then be able to forward their emails to any external email addresses.

What I would like is for the message to arrive from A and be forwarded to a mail enabled Global Distribution Group which has 2 external and 2 internal members in it. However only the 2 internal addresses receive the email messages and not the external addresses.

I do not want to set a forwarder on the Exchange Mailbox to the Distribution Group because all messages from all recipients will be forwarded.

I would like only messages from ONE email recipient to be forwarded on to an external contact.
I have tried using Outlook Rules that when email is received from A it is then forwarded to C(C has been tried as a mail enabled contact and this contact has been added to a mail enabled Distribution Group) and still no luck.

I have failed to get this working so I was hopeful that someone was able to give me some guidance.

I am pretty sure for what you want you would need to enable the auto forwarding global setting. The only work around I can think of is for you to create two local mailboxes for the external recipients with internal company addresses. You would then add these internal mailboxes to the group and set a forward on these internal mailboxes to forward everything out to the external contact that you have created already.

I have tried everything to meet the service requirment but without luck because of my reluctance to tick that global setting box.

In a nutshell, ticking this box for the sake of 1 user vs the security protection of 2400 I guess it is a no brainer. I can do what you said and have an internal mailbox receive and forward this message externally however the recipient of the forwarding message does not want to receive all the messages so I guess there if no filtering for this.

Thanks for your advise
